The plasma display of the present invention is a plasma display in which a dielectric layer and stripe-shaped barrier ribs are formed on a substrate, and it is characterized in that there are inclined regions at the lengthwise direction ends of said barrier ribs and, furthermore, the height (Y) of the inclined regions and the length (X) of the base of the inclined regions are within the range 0.5&lE;X/Y&lE;100. Moreover, the method of the present invention for manufacturing a plasma display is characterized in that the aforesaid stripe-shaped barrier ribs are formed via a process in which a pattern of stripe-shaped barrier ribs having inclined regions at the ends is formed on a substrate using a barrier rib paste comprising inorganic material and organic component, and a process in which said barrier rib pattern is fired.

Polyester film for electrical insulation

Laminated polyphenylene sulfide film and process for producing the same

The present invention provides a polyphenylene sulfide film which consists essentially of a resin composition containing polyphenylene sulfide as major constituent, in which fine particles with an average particle size of 0.05-3 .mu.m are dispersed, the fine particles having a single particle index of not less than 0.5. The polyphenylene sulfide film of the present invention is excellent in not only the slipping property but also the number of electrical insulation defects are extremely small, so that the film of the present invention is useful for the dielectric film of film capacitor with stable initial characteristics. Further, since the film of the present invention is excellent in the slipping property and surface smoothness, so that it is useful as a base film for magnetic recording media with excellent magnetic conversion characteristics and excellent drop out characteristics.

Polyphenylene sulfide film and process of manufacturing the same

A laminate comprising a non-oriented polyphenylenesulfide film and a biaxially oriented polyphenylenesulfide film bonded on at least one surface of the non-oriented polyphenylenesulfide film without using an adhesive, and process for producing it. The delamination of the laminate can be prevented and the tear strength can be increased by suppressing the crystallization of the non-oriented polyphenylenesulfide film. Since an adhesive is not interposed and the main component of the layers of the laminate is polyphenylenesulfide, the laminate can have excellent heat resistance, chemical resistance, electrical insulating property, wet heat resistance and processability with a good balance.

The film of the present invention has an excellent mechanical properties and dimensional stability, as well as excellent clearness.

Biaxially oriented poly-p-phenylene sulfide film

A poly-p-phenylene sulfide resin composition comprising poly-p-phenylene sulfide as a principal component and 0.05 to 40 wt % (based on the total weight of the composition) of at least one metal component selected from the group consisting of zinc, lead, magnesium, manganese, barium and tin. The plastic materials prepared from the composition of this invention are greatly improved in resistance to copper contact and thermal resistance in closed air environment, and therefore are very useful for electrical insulation.

Poly-p-phenylene sulfide resin composition and film made thereof

A polyphenylene sulfide (PPS) molded board reinforced with 15-85 wt. % of glass fibers (GF) having a length of at least 5 mm is provided. The molded board is useful as an insulating substrate of a printed circuit board. The printed circuit board is prepared by compressing under heating a mixture or laminate of PPS and GF to form a composite molded board and, at or after the compression step, bonding a metallic foil to a surface the composite molded board. The printed circuit board is excellent in mechanical properties such as impact resistance, thermal properties such as heat distortion temperature and solder resistance, and adhesion between the insulating substrate and the metallic foil.
